Excuse me, Ruili's sister needs to go through the border checkpoint. What documents do she need to check? Please let me know what to do. Thank you.

I used to work there. If you are only traveling to Gao Jie, you'd better take your ID card with you. If the goods are pulled over, you must go to the customs, inspection and quarantine to go through the inspection procedures. However, if you want to leave this country, you need exit documents, such as the passport of the People's Republic of China and the entry and exit documents of China people in People's Republic of China (PRC) (PRC). Anyway, my sister told me that all the duty-free shops there are open and we can go shopping. Many brands are much cheaper than outside. Have a nice day!
